[0, 1, 2, 1], [2], [5, 2, 3, 3, 6, 7, 7, 7, 7]

    The next example shows the use of multiple values passed to `kth`.

    >>> p2 = np.partition(a, (4, 8))
    >>> p2
    array([0, 1, 2, 1, 2, 3, 3, 2, 5, 6, 7, 7, 7, 7])

    ``p2[4]`` is 2  and ``p2[8]`` is 5.  All elements in ``p2[:4]``
    are less than or equal to ``p2[4]``, all elements in ``p2[5:8]``
    are greater than or equal to ``p2[4]`` and less than or equal to
    ``p2[8]``, and all elements in ``p2[9:]`` are greater than or
    equal to ``p2[8]``.  The partition is::

        [0, 1, 2, 1], [2], [3, 3, 2], [5], [6, 7, 7, 7, 7]
